Initially Configuring the ATM Switch Router
Methods for Configuring the ATM Switch Router
Methods for Configuring the ATM Switch Router
The ATM switch router defaults to a working configuration suitable for most networks. However, you
might need to customize the configuration for your network.
Note
If your Telnet station or SNMP network management workstation is on a different network
from the switch, you must add a static routing table entry to the routing table. See the
“Configuring Static Routes” section on page 10-7.
Terminal Line Configuration (Catalyst 8540 MSR)
The ATM switch router has a console terminal line that might require configuration. For line
configuration, you must first set up the line for the terminal or the asynchronous device attached to it.
For a complete description of configuration tasks and commands used to set up your terminal line and
settings, refer to the Configuration Fundamentals Configuration Guide and Dial Solutions
Configuration Guide.
You can connect a modem to the console port. The following settings on the modem are required:
•
Enable auto answer mode
•
Suppress result codes
You can configure your modem by setting the DIP switches on the modem or by connecting the modem
to terminal equipment. Refer to the user manual provided with your modem for the correct configuration
information.
Note
Because there are no hardware flow control signals available on the console port, the
console port terminal characteristics should match the modem settings.
Terminal Line Configuration (Catalyst 8510 MSR and LightStream 1010)
The ATM switch has two types of terminal lines: a console line and an auxiliary line. For line
configuration, you must first set up the lines for the terminals or other asynchronous devices attached
to them. For a complete description of configuration tasks and commands used to set up your lines,
modems, and terminal settings, refer to the Configuration Fundamentals Configuration Guide and Dial
Solutions Configuration Guide.
Configuration Prerequisites
Consider the following information you might need before you configure your ATM switch router:
•
If you want to configure a BOOTP server to inform the switch of its Ethernet IP address and mask,
you need the Media Access Control (MAC) address of the Ethernet port.
•
If you want to configure a new ATM address for the switch (an autoconfigured ATM address is
assigned by Cisco), you need an ATM address assigned by your system administrator.
•
If you are not using BOOTP, you need an IP address and a netmask address.

Press RETURN to get started!
Note
If an rommon> prompt appears, your switch requires a manual boot to recover. Refer to
the Configuration Fundamentals Configuration Guide for instructions on manually
booting from Flash memory.
Configuring the BOOTP Server
The BOOTP protocol automatically assigns an Ethernet IP address by adding the MAC and IP addresses
of the Ethernet port to the BOOTP server configuration file. When the switch boots, it automatically
retrieves the IP address from the BOOTP server.
The switch performs a BOOTP request only if the current IP address is set to 0.0.0.0. (This is the default
for a new switch or a switch that has had its startup-config file cleared using the erase command.)
To allow your ATM switch router to retrieve its IP address from a BOOTP server, you must first
determine the MAC address of the switch and add that MAC address to the BOOTP configuration file
on the BOOTP server. The following steps provide an example of creating a BOOTP server
configuration file:
Command
Purpose
Step 1
—
Installs the BOOTP server code on the workstation, if it is not
already installed.
Step 2
—
Determines the MAC address from the label on the chassis.
Step 3
—
Adds an entry in the BOOTP configuration file (usually
/usr/etc/bootptab) for each switch. Press Return after each entry
to create a blank line between each entry. See the example
BOOTP configuration file that follows.
Step 4
Switch# reload
Restarts the ATM switch router to automatically request the
IP address from the BOOTP server.

Configuring the ATM Address
The ATM switch router ships with a preconfigured ATM address. The Integrated Local Management
Interface (ILMI) protocol uses the first 13 bytes of this address as the switch prefix that it registers with
end systems. Autoconfiguration also allows the ATM switch router to establish itself as a node in a
single-level Private Network-Network Interface (PNNI) routing domain.
Note
If you chose to manually change any ATM address, it is important to maintain the
uniqueness of the address across large networks. Refer to the Guide to ATM Technology
for PNNI address considerations and for information on obtaining registered ATM
addresses.
For a description of the autoconfigured ATM address and considerations when assigning a new address,
refer to the Guide to ATM Technology.

Initially Configuring the ATM Switch Router
Modifying the Physical Layer Configuration of an ATM Interface
Manually Setting the ATM Address
To configure a new ATM address that replaces the previous ATM address when running IISP software
only, see the “Configuring the ATM Address” section on page 10-5.
To configure a new ATM address that replaces the previous ATM address and generates a new PNNI
node ID and peer group ID, see the “Configuring an ATM Address and PNNI Node Level” section on
page 10-10.
Modifying the Physical Layer Configuration of an ATM Interface
Each of the ATM switch router’s physical interfaces has a default configuration, listed in Chapter 17,
“Configuring Interfaces.” You can accept the defaults, or you can override them by reconfiguring the
physical interface.
The following example describes modifying an OC-3c interface from the default settings to the
following:
•
Disable scrambling cell-payload.
•
Disable scrambling STS-streaming.
•
Change Synchronous Optical Network (SONET) mode of operation from Synchronous Time Stamp
level 3c (STS-3c) mode to Synchronous Transfer Module level 1 (STM-1).
To change the configuration of the example interface, perform the following steps, beginning in global
configuration mode:
Command
Step 1
Purpose
Switch(config)# interface atm card/subcard/port Selects the physical interface to be configured.
Switch(config-if)#
Step 2
Switch(config-if)# no scrambling cell-payload
Disables cell-payload scrambling.
Step 3
Switch(config-if)# no scrambling sts-stream
Disables STS-stream scrambling.
Step 4
Switch(config-if)# sonet stm-1
Configures SONET mode as SDH/STM-1.
Example
The following example shows how to disable cell-payload scrambling and STS-stream scrambling and
changes the SONET mode of operation to Synchronous Digital Hierarchy/Synchronous Transfer
Module 1 (SDH/STM-1) of OC-3c physical interface ATM 0/0/0:
Switch(config)# interface atm 0/0/0
Switch(config-if)# no scrambling cell-payload
Switch(config-if)# no scrambling sts-stream
Switch(config-if)# sonet stm-1
To change any of the other physical interface default configurations, refer to the commands in the
ATM Switch Router Command Reference publication.

Configuring the IP Interface
Note
These IP connections are used only for network management.
To configure the switch to communicate via the Ethernet interface, provide the IP address and subnet
mask bits for the interface.
This section includes the following:
•
Configuring IP Address and Subnet Mask Bits on page 3-8
•
Testing the Ethernet Connection on page 3-9
Configuring IP Address and Subnet Mask Bits
Define subnet mask bits as a decimal number between 0 and 22 for Class A addresses, between 0 and 14
for Class B addresses, or between 0 and 6 for Class C addresses. Do not specify 1 as the number of bits
for the subnet field. That specification is reserved by Internet conventions.
To configure the IP address, perform the following steps, beginning in global configuration mode:
Step 1
Command
Purpose
Switch(config)# interface ethernet 0
Selects the interface to be configured.
Switch(config-if)#
Step 2
Switch(config-if)# ip address ip-address mask
Note
Since release 12.0(1a)W5(5b) of the ATM switch software, addressing the interface on the
processor (CPU) has changed. The ATM interface is now called atm 0, and the Ethernet
interface is now called ethernet 0. The old formats (atm 2/0/0 and ethernet 2/0/0) are still
supported.
Configures the IP and subnetwork address.
Example
The following example shows how to configure interface ethernet 0 with IP address 172.20.40.93 and
subnetwork mask 255.255.255.0:
Switch(config)# interface ethernet 0
Switch(config-if)# ip address 172.20.40.93 255.255.255.0

the switch and a host. The host can reside anywhere in your network. To test for Ethernet connectivity,
use the following EXEC command:
Command
Purpose
ping ip ip-address
Tests the configuration using the ping command. The ping
command sends an echo request to the host specified in the
command line.
The following example show how to test the Ethernet connectivity from the switch to a workstation with
an IP address of 172.20.40.201:
Switch# ping ip 172.20.40.201
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.20.40.201, timeout is 2 seconds:

Configuring Network Clocking
This section describes network clocking configuration of the ATM switch router. Properly
synchronized network clocking is important in the transmission of constant bit rate (CBR) and variable
bit rate real time (VBR-RT) data. For an overview of network clocking and network clock configuration
issues, refer to the chapter “Network Clock Synchronization” in the Guide to ATM Technology.

Initially Configuring the ATM Switch Router
Configuring Network Clocking
Configuring Network Clock Sources and Priorities (Catalyst 8540 MSR)
To configure the network clocking priorities and sources, use the following command in global
configuration mode:
Note
Command
Purpose
network-clock-select {priority {{atm | cbr}
card/subcard/port} | bits {0 | 1} | system} |
bits {e1 | t1} | revertive
Configures the network clock priority.
Specifying the keyword system with the network-clock-select command selects the
route processor reference clock (a stratum 4 clock source) or the network clock module (a
stratum 3 clock source), if present.
Systems equipped with the network clock module can derive clocking from a Building Integrated
Timing Supply (BITS) source. To specify the line type attached to the BITS ports on the network clock
module and to assign a priority to a port, use the following commands in global configuration mode:
Command
Purpose
network-clock-select bits {t1 | e1}
Selects the line type. This command applies to
both BITS ports.
network-clock-select priority bits {0 | 1}
Selects the priority for a BITS port.
Examples
The following example shows how to configure the network clock priorities:
Switch(config)# network-clock-select 1 atm 0/0/0
Switch(config)# network-clock-select 2 atm 0/0/3
Note
This configuration assumes that a full-width module, such as the 4-port OC-12c module,
is being used to derive clocking. If port adapters inserted into carrier modules are used,
the priority 1 and 2 source ports must be on different port adapters.
The following example shows how to configure the network clock to revert to the highest priority clock
source after a failure and takeover by the source with the next lowest priority.
Switch(config)# network-clock-select revertive

Examples
The following example shows how to configure the network clock priorities:
Switch(config)# network-clock-select 1 atm 0/0/0
Switch(config)# network-clock-select 2 atm 0/0/3
The following example shows how to configure the network clock to revert to the highest priority clock
source after a failure and takeover by the source with the next lowest priority.
Switch(config)# network-clock-select revertive
Configuring the Transmit Clocking Source
To configure where each interface receives its transmit clocking, perform the following steps, beginning
in global configuration mode:
Command
Step 1
Purpose
Switch(config)# interface atm card/subcard/port Selects the interface to be configured.
Switch(config-if)#
Step 2
Caution
Switch(config-if)# clock source {free-running |
loop-timed | network-derived}
Configures the interface clock source.
If the Network Clock Distribution Protocol (NCDP) is running on an interface, you should
not override that port’s clock source by configuring it to free-running or loop-timed. Doing
so could cause synchronization problems, particularly in the case of loop-timed, which
could cause a clocking loop to be formed on a link. See the “Configuring Network
Clocking with NCDP” section on page 3-14.

Configuring Network Clocking with NCDP
The Network Clock Distribution Protocol (NCDP) provides a means by which a network can
synchronize automatically to a primary reference source (PRS). To do so, NCDP constructs and
maintains a spanning network clock distribution tree. This tree structure is superimposed on the network
nodes by the software, resulting in an efficient, synchronized network suitable for transport of traffic
with inherent synchronization requirements, such as voice and video.
The following sections provide instructions for configuring NCDP. For a description of how NCDP
works, refer to the Guide to ATM Technology.
Note
The NCDP is intended for use on ATM switch routers equipped with FC-PFQ or with the
network clock module.
NCDP Network Example
Figure 3-1 shows a network of six ATM switch routers with clocking derived from a stratum 3 PRS.
Node A is configured to receive priority 1 clocking on two of its ports, while node B is configured to
receive priority 2 clocking on one of its ports.

constructing the clock distribution tree. To do so, use the following command in global configuration
mode:
Command
Purpose
ncdp source priority {{atm | cbr}
card/subcard/port stratum | bits1 {0 | 1}
stratum | system}
Specifies a priority and source (stratum level
or system) for this interface.
1. Allows you to specify a Building Integrated Timing Supply (BITS) source. This option is available only on the
Catalyst 8540 MSR equipped with the network clock module.
If you do not configure a clock source, NCDP advertises its default source of network clock, which is
its local oscillator; if no nodes in the network have a clock source configured, the tree is built so that it
is rooted at the switch having the highest stratum oscillator (lowest numerical value) and lowest ATM
address.
Example
The following example demonstrates configuring the network clock source, priority, and stratum on
node A in Figure 3-1.
Switch(config)# ncdp source 1 atm 1/0/0 3
Switch(config)# ncdp source 1 atm 3/0/0 3
Configuring Optional NCDP Global Parameters
Optional NCDP parameters you can configure at the global level include the maximum number of hops
between any two nodes, revertive behavior, and the values of the NCDP timers. To change any of these
parameters from their defaults, use the following commands in global configuration mode:
Command
Purpose
ncdp max-diameter hops
Specifies the maximum network diameter for the
protocol. The default maximum network diameter
is 20.
ncdp revertive
Specifies the NCDP as revertive.
ncdp timers {hello | hold} time-in-msec Specifies the values to be used by the NCDP
jitter-percent
timers.

Chapter 3
Initially Configuring the ATM Switch Router
Configuring Network Clocking
When you specify a maximum diameter, you constrain the diameter of the spanning tree by specifying
the maximum number of hops between any two nodes that participate in the protocol. Each node must
be configured with the same maximum network diameter value for NCDP to operate correctly.
When you configure the NCDP as revertive, a clock source that is selected and then fails is selected
again once it has become operational for a period of time. On the Catalyst 8510 MSR and
LightStream 1010 platforms, if NCDP is configured to be revertive, a failed clocking source node after
a switchover is restored to use after it has been functioning correctly for at least 1 minute. On the
Catalyst 8540 MSR the failed source is restored after about 25 seconds. The network clock is, by
default, configured as nonrevertive. Nonrevertive prevents a failed source from being selected again.
Example
The following example shows setting the maximum number of hops to 11 and enabling revertive
behavior:
Switch(config)# ncdp max-diameter 11
Switch(config)# ncdp revertive
Configuring Optional NCDP Per-Interface Parameters
On a per-interface basis, you can enable or disable NCDP, specify the cost metric associated with the
port, and change the control virtual circuit used to transport protocol messages between adjacent
protocol entities. To change any of these parameters from their defaults, use the following commands
in interface configuration mode:
Command
Purpose
ncdp admin-weight weight
Specifies the cost metric associated with the given
port.
ncdp control-vc vpi vci
Specifies the VPI/VCI values to use for control VCs.
The default is 0, 34.
no ncdp
Disables NCDP on the interface.
Example
The following example demonstrates setting the administrative weight on an interface:
Switch(config)# interface atm 0/0/0
Switch(config-if)# ncdp admin-weight 75
Displaying the NCDP Configuration
To display the NCDP configuration, use the following EXEC commands:
Command
Purpose
show ncdp path root
Displays the NCDP clock path from the switch to the
root source.
show ncdp ports
Displays NCDP port information.
show ncdp sources
Displays NCDP clock sources configured on the

Network Clock Services for CES Operations and CBR Traffic
Circuit emulation services-interworking functions (CES-IWF) and constant bit rate (CBR) traffic relate
to a quality of service (QoS) classification defined by the ATM Forum for Class A (ATM adaptation
layer 1 [AAL1]) traffic in ATM networks. In general, Class A traffic pertains to voice and video
transmissions, which have particular clocking requirements. For details, refer to Chapter 18,
“Configuring Circuit Emulation Services.”

Chapter 3
Initially Configuring the ATM Switch Router
Configuring Network Routing
Configuring Network Routing
The default software image for the ATM switch router contains the Private Network-Network Interface
(PNNI) routing protocol. The PNNI protocol provides the route dissemination mechanism for complete
plug-and-play capability. The following section, “Configuring ATM Static Routes for IISP or PNNI,”
describes modifications that can be made to the default PNNI or Interim-Interswitch Signalling Protocol
(IISP) routing configurations.
For routing protocol configuration information, refer to Chapter 9, “Configuring ILMI,”and Chapter 10,
“Configuring ATM Routing and PNNI.”
Configuring ATM Static Routes for IISP or PNNI
Static route configuration allows ATM call setup requests to be forwarded on a specific interface if the
addresses match a configured address prefix. To configure a static route, use the following command in
global configuration mode:
Note
Command
Purpose
atm route addr-prefx atm card/subcard/port
Specifies a static route to a reachable address
prefix.
An interface must be User-Network Interface (UNI) or Interim Interswitch Signalling
Protocol (IISP) to be configured with static route. Static routes configured as PNNI
interfaces default as down.
The following example shows how to use the atm route command to configure the 13-byte peer group
prefix = 47.0091.8100.567.0000.0ca7.ce01 at interface ATM 3/0/0:
Switch(config)# atm route 47.0091.8100.567.0000.0ca7.ce01 atm 3/0/0
Switch(config)#
Configuring System Information
Although not required, the system clock and hostname should be set as part of the initial system
configuration. To set these system parameters, perform the following steps, beginning in privileged
EXEC mode:
Command
Purpose
Step 1
Switch# clock set hh:mm:ss day month year
Sets the system clock.
Step 2
Switch# configure terminal
Switch(config)#
Enters global configuration mode from the
terminal.
Switch(config)# hostname name
Sets the system name.

Configuring Online Diagnostics (Catalyst 8540 MSR)
Online and insertion diagnostics detect and report hardware failures in the Catalyst 8540 MSR during
system bootup and operation.
The online diagnostics on the Catalyst 8540 MSR provide the following types of tests:
Note
•
Access tests between the route processor and the switch processors, feature cards, port adapters,
and interface modules
•
Online insertion and removal (OIR) diagnostic tests
•
Snake tests through the switch router to ensure connectivity between the ports
Online diagnostics tests only run on the primary route processor.
Access Test (Catalyst 8540 MSR)
The access tests ensure connectivity at a configurable interval between the primary route processor and
the following:
•
Active switch processors
•
Standby switch processor, if it is present
•
Feature cards
•
Carrier modules
•
ATM port adapters
•
ATM and Layer 3 interface modules
•
ATM router modules
When the access test detects a hardware failure, the system issues an error message to the console.
If the access test detects a hardware problem with an active switch processor, the standby switch
processor, if it is present, automatically takes over and becomes an active switch processor. The system
generates an SNMP trap when the switchover occurs.
Note
The access test does not support the network clock module.

Chapter 3
Initially Configuring the ATM Switch Router
Configuring Online Diagnostics (Catalyst 8540 MSR)
OIR Test (Catalyst 8540 MSR)
Online insertion and removal (OIR) tests check the functioning of the switch fabric and interfaces on a
per-port basis. The switch router performs these tests when the system boots up and when you insert a
port adapter or interface module into a slot. The OIR test sends a packet to the interface loopback and
expects to receive it back within a certain time period. If the packet does not reach the port within the
expected time period, or the route processor receives a corrupted packet, the system issues an error
message to the console, generates an SNMP trap, and brings the port to an administrative down state.
Note
The size of the packet used in the test is configurable.
The OIR tests support all ATM port adapters, all ATM interface modules, and all Layer 3 interface
modules except the 8-port Gigabit Ethernet. It does not support ATM router modules.
Snake Test (Catalyst 8540 MSR)
The snake test detects and reports port-to-port connectivity failures. The snake test establishes a
connection across all the active ports in the switch router, originating and terminating at the primary
route processor. The route processor establishes a connection by sending a packet to each port in turn,
which then terminates at the route processor. If the packet does not reach the route processor within the
expected time period, or the received packet is corrupted, further testing is performed to isolate and
disable the port causing the problem.The size of the packet and frequency of the test are configurable
to minimize the impact on system performance.
The snake test supports all ATM interface modules and enhanced Gigabit Ethernet interface modules.
It does not support ATM port adapters, ATM router modules, 16-port 10/100 Fast Ethernet interface
modules, 2-port Gigabit Ethernet interface modules, or 8-port Gigabit Ethernet interface modules.
Note
The snake test does not support ATM port adapters because of a hardware limitation in the
carrier module.
Configuring Online Diagnostics (Catalyst 8540 MSR)
To configure online diagnostics, use the following global configuration commands:
Command
Purpose
diag online
Enables all of the online diagnostic tests.
diag online access
Enables only the access diagnostic test.
diag online access freq [seconds]
Configures the frequency of the access diagnostic
tests. The default frequency is every 10 seconds.
diag online oir

Chapter 3
Initially Configuring the ATM Switch Router
Configuring Redundancy and Enhanced High System Availability (Catalyst 8540 MSR)
Route Processor Redundant Operation (Catalyst 8540 MSR)
The ATM switch router supports fault tolerance by allowing a secondary route processor to take over if
the primary fails. This secondary, or redundant, route processor runs in standby mode. In standby mode,
the secondary route processor is partially booted with the Cisco IOS software; however, no
configuration is loaded.
At the time of a switchover, the secondary route processor takes over as primary and loads the
configuration as follows:
•
If the running configuration between the primary and secondary route processors match, the new
primary uses the running configuration file
•
If the running configuration between the primary and secondary route processors do not match, the
new primary uses the last saved configuration file in its nonvolatile random-access memory
(NVRAM) (not the NVRAM of the former primary)
The former primary then becomes the secondary route processor.
Note
If the secondary route processor is unavailable, a major alarm is reported. Use the show
facility-alarm status command to display the redundancy alarm status.
When the ATM switch router is powered on, the two route processors go through an arbitration to
determine which is the primary route processor and which is the secondary. The following rules apply
during arbitration:
•
A newly inserted route processor card always comes up as the secondary, except in cases where the
newly inserted card is the only one present.
•
If the configuration is corrupted, one of the route processors comes up as primary, allowing you to
correct the situation manually.
•
The primary route processor when the ATM switch is powered off continues as the primary when
the ATM switch is powered on.
•
If none of the above conditions is true, the route processor in slot 4 becomes the primary.
During normal operation, the primary route processor is booted completely. The secondary CPU is
partially up, meaning it stops short of parsing the configuration. From this point, the primary and
secondary processors communicate periodically to synchronize any system configuration changes.
The following situations can cause a switchover of the primary route processor:
•
The primary route processor is removed or swapped. When a route processor functioning as
primary is removed, the secondary takes over. The ATM switch router is now nonredundant until a
second route processor is inserted.
•
The primary route processor is rebooted. When a route processor functioning as primary is
rebooted, the secondary takes over.
•
The primary route processor fails. The secondary route processor takes over as primary, using the
last saved configuration (or the current running configuration if they have been synchronized with
the sync config command).
•
A switchover is manually forced with the redundancy force-failover main-cpu command.
When a switchover occurs, permanent virtual channels (PVCs) are preserved; switched virtual channels
(SVCs) and Integrated Local Management Interface (ILMI) address states are lost, and then restored
after they are dynamically redetermined.

Chapter 3
Initially Configuring the ATM Switch Router
Configuring Redundancy and Enhanced High System Availability (Catalyst 8540 MSR)
Configuring Route Processor Redundancy (Catalyst 8540 MSR)
For redundant operation, the following requirements must be met:
•
Two route processors and three switch cards are required.
•
The route processors must have identical hardware configurations. This includes variables such as
DRAM size, presence or absence of network clock modules, and so on.
•
Both route processors must have the same functional image. For more information, see the
“Maintaining Functional Images (Catalyst 8540 MSR)” section on page 22-5.
•
Both route processors must be running the same system image.
•
Both route processors must be set to autoboot (a default setting).
If these requirements are met, the ATM switch router runs in redundant mode by default. The tasks
described in the following sections are optional and used only to change nondefault values.
Forcing a Route Processor Switchover (Catalyst 8540 MSR)
You can manually force the secondary route processor to take over as primary. To do so, use the
following privileged EXEC command:
Command
Purpose
redundancy force-failover main-cpu
Forces a route processor switchover.
As long as you have not changed the default configuration register setting, which is set to autoboot
by default, the secondary route processor (formerly the primary) completes the boot process from
standby mode.
If you have changed the default configuration register value, you can change it back to autoboot, and
ensure that the correct system image is used at startup, by performing the following steps, beginning in
global configuration mode:
Command
Purpose
Step 1
Switch(config)# config-register 0x2102
Sets the config register for autoboot.
Step 2
Switch(config)# boot system {[device:]filename Specifies the system image file to load at startup.
[hostname | ip-address] | flash [device:][filename]
| mop filename [type] [card/subcard/port] | rcp
filename [ip-address] | rom | tftp filename
[hostname | ip-address]}
Step 3
Switch(config)# end
Returns to privileged EXEC mode.
Switch#
Step 4
Switch# copy running-config startup-config
Note
If the secondary route processor remains in ROM monitor mode, you can manually boot
the processor from either the bootflash or Flash PC card.
Saves the configuration to NVRAM.

Caution
If no system image is specified in the startup configuration, the ROM monitor
automatically boots the first system image on the Flash PC card in slot0. If there is no
system image on the Flash PC card, or the Flash PC card is not available, the ROM monitor
boots the first system image in bootflash. If there is no system image in bootflash, the
switch remains in ROM monitor mode.
Displaying the Configuration Register Value
To display the configuration register value, use the following privileged EXEC command:
Command
Purpose
show version

Synchronizing the Configurations (Catalyst 8540 MSR)
During normal operation, the startup and running configurations are synchronized by default between
the two route processors. In the event of a switchover, the new primary route processor uses the current
configuration. Configurations synchronize either immediately from the command line or during route
processor switchover.

Initially Configuring the ATM Switch Router
Configuring Redundancy and Enhanced High System Availability (Catalyst 8540 MSR)
Immediately Synchronizing Route Processor Configurations (Catalyst 8540 MSR)
To immediately synchronize the configurations used by the two route processors, use the following
privileged EXEC command on the primary route processor:
Command
Purpose
redundancy manual-sync {startup-config |
running-config | both}
Immediately synchronizes the configuration.
Example
In the following example, both the startup and running configurations are synchronized immediately:
Switch# redundancy manual-sync both
Synchronizing the Configurations During Switchover (Catalyst 8540 MSR)
To manually synchronize the configurations used by the two route processors during a switchover,
perform the following steps on the primary route processor, beginning in global configuration mode:
Step 1
Command
Purpose
Switch(config)# redundancy
Enters redundancy configuration mode.
Switch(config-r)#
Step 2
Switch(config-r)# main-cpu
Enters main-cpu configuration submode.
Switch(config-r-mc)#
Step 3
Switch(config-r-mc)# sync config {startup |
running | both}1
Synchronizes either or both configurations during
switchover or writing the files to NVRAM.
Step 4
Switch(config-r-mc)# end
Returns to privileged EXEC mode.
Switch#
Step 5
Switch# copy running-config startup-config
Forces a manual synchronization of the
configuration files in NVRAM.
Note
1.
This step is unnecessary to synchronize
the running configuration file in DRAM.
Alternatively, you can force an immediate synchronization by entering the redundancy manual-sync command in
privileged EXEC mode.
Example
In the following example, both the startup and running configurations are synchronized:
Switch(config)# redundancy
Switch(config-r)# main-cpu
Switch(config-r-mc)# sync config both
Switch(config-r-mc)# end
Switch# copy running-config startup-config

Preparing a Route Processor for Removal (Catalyst 8540 MSR)
Before removing a route processor that is running the IOS in secondary mode, it is necessary to change
it to ROM monitor mode. You could use the reload command to force the route processor to ROM
monitor mode but the automatic reboot would occur and you would interrupt switch traffic.
Caution
If you fail to prepare the secondary route processor for removal, the traffic through the
switch could be interrupted.

Chapter 3
Initially Configuring the ATM Switch Router
Configuring Redundancy and Enhanced High System Availability (Catalyst 8540 MSR)
Configuring Switch Fabric Enhanced High System Availability Operation
(Catalyst 8540 MSR)
Slots 5, 6, and 7 in the ATM switch router chassis can accommodate either two or three switch
processor cards, with a switching capacity of 10 Gbps each. The possible configurations are as follows:
•
Two switch processors—20 Gbps non-EHSA switching fabric (no spare)
•
Three switch processors—20 Gbps EHSA switching fabric (one spare)
When three switch processors are installed, two are active at any time, while the third runs in standby
mode. By default, switch processors 5 and 7 are active and switch processor 6 is the standby. To force
the standby switch processor to become active, use the redundancy preferred-switch-card-slots
command.
Caution
Do not hot swap an active switch processor module before putting it in standby mode.
Removing an active switch processor breaks active connections and stops the flow of
traffic through the switch. Put an active switch in standby mode using the redundancy
preferred-switch-card-slots command before removing it from the chassis.
When a switchover to the standby switch processor occurs, the system resets and all connections are
lost. When the system comes up again, all PVCs and SVCs are reestablished automatically.
Configuring Preferred Switching Processors (Catalyst 8540 MSR)
To configure which two of the three switch processors are active and which runs in standby mode, use
the following privileged EXEC command on the primary route processor:
Command
Purpose
redundancy preferred-switch-card-slots
{5 | 6 | 7} {5 | 6 | 7}
Configures the active and standby switch
processors.
Example
In the following example, the preferred switch processors are configured to be in slots 5 and 7 with the
slot 6 switch processor running in standby mode:
Switch# redundancy preferred-switch-card-slots 5 7
The preferred switch cards selected are already active
Note
The preferred switch card slot configuration reverts to the default configuration when the
switch is power cycled.

Configuring SNMP and RMON
SNMP is an application-layer protocol that allows an SNMP manager, such a network management
system (NMS), and an SNMP agent on the managed device to communicate. You can configure
SNMPv1, SNMPv2, or both, on the ATM switch router. Remote Monitoring (RMON) allows you to see
the activity on network nodes. By using RMON in conjunction with the SNMP agent on the ATM switch
router, you can monitor traffic through network devices, segment traffic that is not destined for the
ATM switch router, and create alarms and events for proactive traffic management.
For detailed instructions on SNMP and general RMON configuration, refer to the Configuration
Fundamentals Configuration Guide. For instructions on configuring ATM RMON, refer to Chapter 14,
“Configuring ATM Accounting and ATM RMON.”
Storing the Configuration
When autoconfiguration and any manual configurations are complete, you should copy the
configuration into nonvolatile random-access memory (NVRAM). If you should power off your
ATM switch router prior to saving the configuration in NVRAM, all manual configuration changes
are lost.
To save the running configuration to NVRAM, use the following command in privileged EXEC mode:
Command
Purpose
copy system:running-config
nvram:startup-config
Copies the running configuration in system
memory to the startup configuration stored in
NVRAM.

Testing the Ethernet Connection
After you have configured the IP address(es) for the Ethernet interface, test for connectivity between the
switch and a host. The host can reside anywhere in your network. To test for Ethernet connectivity, use
the following user EXEC command:
Command
Purpose
ping ip ip-address
Tests the configuration using the ping
command. The ping command sends an echo
request to the host specified in the command .
For example, to test Ethernet connectivity from the switch to a workstation with an IP address of
172.20.40.201, enter the command ping ip 172.20.40.201. If the switch receives a response, the
following message displays:
Switch# ping ip 172.20.40.201
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.20.40.201, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/202/1000 ms
